# Tier 4: Monitoring & Feedback (Governance Layer)
|
|
|
|
Tier 4 acts as the "supervisor" of the entire architecture. It ensures the system is performing correctly, ethically, and efficiently, while providing a path for continuous evolution.
|
|
|
|
## Key Responsibilities
|
|
|
|
### 1. Performance Monitoring
|
|
* Track latency, token usage, and error rates across all tiers.
|
|
* Identify bottlenecks (e.g., a Tier 2 specialist that is consistently slow).
|
|
|
|
### 2. Evaluation & Feedback
|
|
* Collect explicit user feedback (e.g., "Good/Bad" ratings).
|
|
* Perform automated evaluation using "LLM-as-a-judge" to score responses based on accuracy, tone, and safety.
|
|
* Log failures for manual review and human-in-the-loop (HITL) intervention.
|
|
|
|
### 3. Error Analysis & Root Cause
|
|
* Analyze why specific routes failed or why a specialist produced a low-quality output.
|
|
* Maintain a "lesson learned" database to inform future system prompts or fine-tuning.
|
|
|
|
### 4. Continuous Improvement
|
|
* Inform the retraining or fine-tuning of Tier 2 models based on real-world usage patterns.
|
|
* Optimize Tier 1 routing logic based on success/failure metrics.
|
|
|
|
## Tools & Techniques
|
|
* **Logging/Observability:** (e.g., LangSmith, Weights & Biases, custom JSON-L logs).
|
|
* **A/B Testing:** Compare different model versions or routing strategies.
|
|
* **Red Teaming:** Proactively test the system for vulnerabilities and biases.
